Description

Technical Field

[0001] The invention belongs to the technical field of control cabinets, and in particular relates to a power system control cabinet with a jet cleaning structure. Background Art

[0002] In the power system, the control cabinet plays a vital role, and a large number of electrical components and circuits are integrated inside. However, in the long-term operation process, the outdoor control cabinet is often in a harsh environment (such as wind and sand), which leads to the accumulation of dust inside the control cabinet. The accumulation of dust will not only affect the heat dissipation performance of the electrical components, causing the component temperature to rise and increase energy consumption, but also may cause safety hazards such as short circuits, seriously affecting the stable operation of the power system. Therefore, it is necessary to set a jet cleaning structure inside the control cabinet. For example, the announcement is: CN115313177A, which discloses a power system control cabinet with a jet cleaning structure.

[0003] Existing jet cleaning structures generally have jet cleaning directly facing the electrical components or jet cleaning from the side of the electrical components. However, when jet cleaning directly facing the electrical components, dust is easily lifted up in the air due to the direct impact of the airflow. The lifted dust may adhere to the surface of the electrical components again under the action of the airflow, causing the dust to be lifted up again, thereby causing pollution to the electrical components; jet cleaning from one side of the electrical components has greater limitations on the cleaning of the electrical components. Due to factors such as the shape, structure and installation position of the electrical components, it is difficult for the jet cleaning on one side to fully cover all surfaces. This results in the other side of the electrical components being unable to be effectively cleaned, which will still cause electrical failures and reduce the reliability and stability of the power system.

[0004] Therefore, a power system control cabinet with a jet cleaning structure is proposed. Summary of the invention

[0023] A plurality of rotary air-spraying and air-inhaling mechanisms 6 are respectively arranged on both sides of the electrical components inside the cabinet 1, and the plurality of rotary air-spraying and air-inhaling mechanisms 6 are distributed toward the electrical components inside the cabinet 1. A protective isolation net 14 is fixedly provided on both sides of the interior of the cabinet 1 and between the rotary air-spraying and air-inhaling mechanisms 6 and the electrical components. The protective isolation net 14 can isolate and protect the rotary air-spraying and air-inhaling mechanisms 6 from the electrical components to prevent the rotary air-spraying and air-inhaling mechanisms 6 from being touched during the installation and operation of the electrical components, or the rotary air-spraying and air-inhaling mechanisms 6 from touching the electrical components during the rotation process. A condensing air box 7 is fixedly provided on the top of the cabinet 1, and air pipes 8 are fixedly provided at both ends of the condensing air box 7.

The rotary drive mechanism 9 includes a driving electric push rod 91 fixedly arranged on the top of the cabinet 1, and a connecting plate 92 is fixedly arranged on the movable end of the driving electric push rod 91 in a horizontal direction. Connecting rods 93 extending to both sides of the interior of the cabinet 1 are fixedly arranged on both sides of the lower surface of the connecting plate 92, and racks 94 are fixedly arranged at the lower ends of the two connecting rods 93. Multiple gears 95 are meshed on one side of the two racks 94, and a rotating shaft 96 rotatably connected to the inner wall of the cabinet 1 is fixedly arranged inside the multiple gears 95.

The upper air suction head 61 is arranged so that the blowing intensity of the upper air suction head 61 is the largest, the blowing intensity of the middle air suction head 62 is medium, and the blowing intensity of the lower air suction head 63 is the smallest. Since the upper air suction head 61, the middle air suction head 62 and the lower air suction head 63 spray air to electrical components at different positions, electrical components that are farther away require a higher jet intensity to ensure the effect of jet dust removal, and electrical components that are closer require a lower jet intensity to ensure the effect of jet dust removal.

[0026] Two filters 12 are fixedly arranged on both sides of the cabinet 1, and the two filters 12 are respectively arranged on the two air pipes 8. The filter 12 includes a filter shell 121 fixedly arranged on the top of the cabinet 1. A filter screen 122 is vertically fixed inside the filter shell 121. A cleaning mechanism 123 is arranged on the top of the filter shell 121 and is arranged on the side of the filter screen 122. The cleaning mechanism 123 is arranged corresponding to the position of the connecting plate 92. A dust cleaning sealing cover 124 is arranged on the side wall of the filter shell 121.

[0028] The operating principle of the present invention is described as follows: the staff first transports the cabinet 1 to the outdoors, and then pre-injects a concrete base outdoors. The location of the base is generally close to the concentrated area of ​​​​the power equipment, such as the transformer and switch cabinet in the substation. Then the cabinet 1 is installed on the top of the base. During the installation process, it is necessary to ensure that the control cabinet is installed horizontally. It can be calibrated by tools such as a level to prevent the normal operation of the internal electrical components from being affected by the tilt. After the installation of the cabinet 1 is completed, the cabinet door 2 is opened, and the electrical components (circuit breakers, contactors, relays, fuses, transformers, controllers, sensors and other components) are installed inside the cabinet 1. Finally, the cabinet door 2 is locked. Under normal use (not in summer or when a small number of electrical components are running), the small amount of heat generated by the electrical components during operation can be dissipated through the ventilation windows on both sides by gas flow, thereby ensuring the operating stability of the electrical components inside the cabinet 1; When the dust inside the cabinet 1 is relatively large (indicating that the dust concentration in the air outside the cabinet 1 is also relatively high, such as sandstorm weather), the dust sensor 3 can detect the dust concentration (the light source of the dust sensor 3 emits light, and the light is scattered when it is irradiated on dust particles. The more dust particles there are, the stronger the scattered light is. The photoelectric detector of the dust sensor 3 converts the received scattered light signal into an electrical signal, and then feeds the electrical signal back to the PLC controller 13). When the dust concentration reaches the threshold set by the dust sensor 3, the dust sensor 3 feeds back an electrical signal to the PLC controller 13. The PLC controller 13 controls and turns on the servo fan 10 to rotate forward for forward jet cleaning, so that the air pipe 8 on the left side can suck the gas inside the cabinet 1, and at the same time, the air pipe 8 on the right side can blow air toward the inside of the cabinet 1. The air pipes 8 on both sides cooperate with the upper spray suction head 61, the middle spray suction head 62 and the lower spray suction head 63, and the right side The upper suction head 61, the middle suction head 62 and the lower suction head 63 of the air pipe 8 spray gas from one side to the surface of the electrical components, so that the dust attached to the surface of the electrical components is blown up, and the upper suction head 61, the middle suction head 62 and the lower suction head 63 on the left side suck the blown dust gas into the inside of the air pipe 8 on the left side. Three upper suction heads 61, three middle suction heads 62 and three lower suction heads 63 are arranged on the left and right sides of the cabinet 1, so that the electrical components are The air components can be fully covered by the jet [the air inlet diameters of the upper jet suction head 61, the air inlet diameters of the middle jet suction head 62 and the air inlet diameters of the lower jet suction head 63 are decreased from large to small, so that the blowing intensity of the upper jet suction head 61 is the largest, the blowing intensity of the middle jet suction head 62 is medium and the blowing intensity of the lower jet suction head 63 is the smallest. Since the upper jet suction head 61, the middle jet suction head 62 and the lower jet suction head 63 spray air to electrical components at different positions (such as Figure 8, the upper spray suction head 61, the middle spray suction head 62 and the lower spray suction head 63 decrease in height from top to bottom, and the upper spray suction head 61 has a larger distance from the electrical components to be cleaned by the jet than the middle spray suction head 62, and the middle spray suction head 62 has a larger distance from the electrical components to be cleaned by the jet than the lower spray suction head 63), so the upper spray suction head 61 needs a higher jet intensity to ensure the effect of jet dust removal, and the lower spray suction head 63 needs a lower jet intensity to ensure the effect of jet dust removal. This structural design can not only improve the cleaning effect, but also save power energy loss and improve the cleaning efficiency. The air is then filtered through the filter 12, and the air can be filtered through the filter 122 The dust in the cabinet is filtered and then flows back to the inside of the cabinet 1 after being filtered, so that the gas inside the cabinet 1 is circulated and filtered to ensure the cleanliness of the gas. There is no need to discharge a large amount of gas outside the cabinet 1 into the inside of the cabinet 1, which can prevent the dust in the external gas from polluting the electrical components again (it should be emphasized here that since ventilation windows are provided on both sides of the cabinet 1, when the electrical components are jet-cleaned, a small amount of gas from the outside of the cabinet 1 will also enter because the gas is flowing, but the amount of gas is relatively small, and the dust in the gas will pollute the electrical components to a lesser extent. Moreover, the temperature of the small amount of gas outside the cabinet 1 is relatively low, and the heat dissipation effect of the electrical components is also guaranteed after entering the inside of the cabinet 1); During the forward jet cleaning process, the PLC controller 13 controls the driving electric push rod 91 to extend and reciprocate. The driving electric push rod 91 can drive the connecting plate 92 and the connecting rods 93 and racks 94 on both sides to move up and down. The racks 94 on both sides can drive the multiple gears 95 to reciprocate accordingly, so that the rotating block 97 on the rotating shaft 96, the hollow plate 98 and the rotating spray and suction mechanism 6 can reciprocate together, and the surface of the electrical components can be jet-cleaned at multiple angles, thereby improving the cleaning effect. When the connecting plate 92 moves downward, the connecting plate 92 will squeeze the slide bar 125 on the top of the filter housing 121, and the slide bar 125 will overcome the elastic force of the second spring 128 and move downward, and the slide bar 125 can drive the cleaning brush 126 to move on the surface of the filter screen 122, and can clean the foreign particles attached to the aperture of the filter screen 122, so as to ensure that the filter screen 122 continues to filter the gas. When the connecting plate 92 moves upward, the second spring 128 can exert an upward elastic force on the slide bar 125 and reset it to ensure that the connecting plate 92 presses the slide bar 125 again, thereby realizing the function of reciprocating cleaning of the filter screen 122, and the cleaned foreign particles will fall on the bottom of the filter housing 121, and after the cleaning is completed, the dust cleaning sealing cover 124 can be opened manually for cleaning; After 10 minutes of forward jet cleaning, the PLC controller 13 will automatically control the servo fan 10 to rotate in the opposite direction and perform reverse jet cleaning for 5 minutes (because the forward jet cleaning has cleaned most of the dust on the surface of the electrical components, the amount of dust in the reverse jet cleaning is small, there is no need to increase the working time, and the loss of electric energy is reduced). During the reverse jet cleaning, the rotary jet suction mechanism 6 on the right side sucks gas, and the rotary jet suction mechanism 6 on the left side sprays gas, so that the gas can be sprayed from the left side inside the cabinet 1 and the surface of the electrical components is cleaned, so that the surface of the electrical components is fully cleaned. After the dust on the surface of the electrical components is cleaned, the heat dissipation efficiency of the electrical components is guaranteed, the energy consumption of the electrical components is reduced, and the operating stability of the electrical components is improved. If the windy and sandy weather is relatively bad and the amount of dust on the surface of the electrical components is large, it is necessary to alternately use the forward jet cleaning and the reverse jet cleaning for multiple times until the surface of the electrical components is cleaned; When the humidity inside the cabinet 1 is high, the humidity sensor 5 can always detect the humidity inside the cabinet 1 (there is a layer of hygroscopic material inside the humidity sensor 5, such as a high molecular polymer. When the humidity inside the cabinet 1 changes, the hygroscopic material will absorb or release water molecules, and the circuit inside the humidity sensor 5 will convert the capacitance change into an electrical signal). When the humidity value reaches the threshold value set by the humidity sensor 5, the humidity sensor 5 will feedback an electrical signal to the PLC controller 13, and the PLC controller 13 will turn on the servo fan 10 to rotate forward and connect the power of the refrigeration tube 111. The servo fan 10 can absorb the moisture inside the cabinet 1 through the surface of the refrigeration tube 111, so that the moisture is condensed and liquefied into water droplets through the refrigeration tube 111 (the surface temperature of the refrigeration tube 111 is low. When the hot moisture contacts the tube wall of the refrigeration tube 111, the moisture temperature drops below the dew point temperature, and the water vapor will gather to form water droplets and adhere to the surface of the refrigeration tube 111). The dehumidified gas returns to the inside of the cabinet 1 to ensure the operating stability of the electrical components inside the cabinet 1. The blades of the servo fan 10 can drive the cam 115 to rotate together when rotating, so that the raised part of the cam 115 pushes the top block 114 upward, so that the refrigeration tube 111 can be pushed to overcome the elastic force of the first spring 113 and move upward. When the raised part of the cam 115 is no longer in contact with the refrigeration tube 111, the elastic force of the first spring 113 exerts a downward elastic force on the refrigeration tube 111, so that the refrigeration tube 111 quickly moves downward and resets, so that the refrigeration tube 111 can be circulated to reciprocate up and down, increase the contact area between the moisture and the refrigeration tube 111, and improve the dehumidification effect of the moisture. At the same time, when the refrigeration tube 111 moves up and down, the water droplets attached to the surface can be shaken off, and finally flow to the drain pipe 117 through the guide table 116, which is convenient for manual centralized discharge. When the temperature inside the cabinet 1 is high (in summer or when a large number of electrical components are working at a high temperature at the same time), the temperature sensor 4 can always detect the humidity inside the cabinet 1 [the temperature sensor 4 can directly contact the internal air or objects, and will change its electrical characteristics according to its own temperature changes (changes in the resistance value of the thermal resistor, changes in the thermoelectric potential of the thermocouple), and convert these changes into electrical signals through the connected circuit]. When the temperature value reaches the threshold set by the temperature sensor 4, the temperature sensor 4 feeds back an electrical signal to the PLC controller 13, and the PLC controller 13 turns on the servo fan 10 for forward rotation and connects the power supply of the refrigeration pipe 111. The gas can be cooled through the refrigeration pipe 111, so that the electrical components inside the cabinet 1 can be rapidly cooled, thereby extending the service life of the electrical components.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
